You can use the Mapping Editor to create and visualize replications.
A simple data replication can be designed as follows:
Data contained in a source database is transferred to the replication process via a source data connection and published (publication). The published data can be subscribed (subscription) by a target database using a target data connection.
The Mapping Editor accessible from the replication process contextual menu (let us call it the Replication Process Mapping Editor (RPME)) allows you to visualize and create the publication — subscription couple using mappings. A mapping can be a publication, an article, and article column or a procedure depending on the source data you want to replicate.
The mapping is materialized by a graphical link joining source and target.
